摘要:
本文对ＴｉＯ２－ＳＯ２－４型固体超强酸催化剂的制备进行了研究，并应用于苄基甲苯的合成。考察了Ｈ２ＳＯ４浓度，与Ｈ２ＳＯ４接触时间、焙烧温度等条件对催化剂活性的影响。通过改变催化剂用量、反应温度对产品收率的影响，由正交实验确定了最佳工艺条件。在最佳工艺条件下，对二元及三元复合型固体超强酸催化剂的活性也进行了一些研究。实验结果表明，ＴｉＯ２－ＳＯ２－４型固体超强酸催化剂及其复合型催化剂可用于苄基甲苯的合成，具有工业摧广价值。
Abstract:
This article studies the preparation of the TIO2 -SO2-4 solid super -strong acid catalyst, and is used in the synthesis of cymbal tactics. The H2SO4 concentration was inspected, and the effects of contact time such as H2SO4 and the roasting temperature on catalyst activity. By changing the impact of the amount of catalyst and the reaction temperature on product revenue, the best process conditions are determined by the orthogonal experiment. Under the best process conditions, some research on the activity of binary and three -yuan composite solid solid super -high acid catalysts. The experimental results show that the TIO2 -SO2-4 solid super -strong acid catalyst and its composite catalyst can be used in the synthesis of pyrinated titthopine, which has industrial extensive value.
